摘要:

针对齿轮加工机床中展成和差动运动对多轴联动速度和精度的严格要求,在分析齿轮加工工艺的基础上构建了软件电子齿轮箱(EGB)的理论模型,研究了其在基于ARM+DSP+FPGA嵌入式数控系统中的实现方法及电子齿轮箱开关过程中的速度处理策略,详细分析了数控系统中数据信息的传递过程。最后,设计了专用带参数的G代码,通过NC编程实现对电子齿轮箱的控制,并在自行研发的滚齿数控系统中实现了电子齿轮箱的NC控制。

Abstract:

Division of teeth pitch and differentiation of gear cutting machine are strict with the accuracy of multi-axis speed control. The paper built a theoretical model of software EGB based on the analyses of hobbing technology. Implementation methods of software EGB in embedded NC system were researched based on the hardware of ARM+DSP+FPGA. Strategy of acceleration/deceleration was considered at the start and cancellation stages of EGB synchronization control. The data flow among the modules in NC system was analyzed in detail. Moreover the special G codes with parameters were designed, and the EGB control through NC programming was realized in a home made NC system.

Key words: electronic gearbox(EGB), gear-hobbing, inner-link transmission, acceleration and deceleration
